DDSF169 Single-phase Electronic Multi-rate KWH Meter.

Application: DDSF169 single-phase electronic multi-rate electronic energy meter is a new generation product,which is developed lately by absorbing the opinions from the experts of power supply system and users in public as well as foreign new technology. The product meets the requirements of GB/T17215-2002 rade land2 Static AC Active Watt hour Meter and GB/T15284-2002 Multi-rate (Time Sharing) Watt-hour Meter. Except for the fundamental functions of time sharing measurement,it can still be provided with other additional functions(such as maximum demand,infrared meter copying and stirring ,etc) to meet the requirements of different users.

Main characteristics:

1.Long service life and excellent performance owing to the industrial grade chip,liquid crystal display(LCD),crystal oscillator,etc.

2. High in integration,simple in peripheral circuit ,rational in distribution,good in integrity,small in size and easy to installation.
